Occlusion Horizons for Driving Through Urban Scenery

We present a rapid occlusion culling algorithm specifically designed for urban environments. For each frame, an occlusion horizon is being built on-the-fly during a hierarchical front-to-back traversal of the scene. All conservatively hidden objects are culled, while all the occluding impostors of all conservatively visible objects are added to the 2½D occlusion horizon. Our framework also support

Commodity Currencies vs Fiat Money - Automaticity vs Embedment

Commodity currencies have been stood against fiat money in the discourses on the history of money, implying a development from primitive forms of money – which needed anchor in a real commodity to gain acceptance, for instance gold, silver or copper – to a more sophisticated monetary regime based solely on confidence and trust. This paper argues that the idea of a gradual replacement of the former

Models for Wet Scrubbing of SO2 and NOx

Popular Abstract in Swedish Arbetet har bestått av att dels experimentellt samt dels med hjälp av matematiska modeller undersöka och kartlägga förloppen för nya samt "gamla" metoder att rena rökgaser från kol- och olje eldade kraftverk.Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. Many of the techniques available today have been on the market for a long time, however, most of them still have a potential for improvement. To be able t

Social Media and Parliamentary Infighting: Digital naturals in the Swedish Riksdag?

Research on the use of social network sites by elected politicians has often been narrowed down to behaviour during election campaigns and using social media as a way of reaching voters and journalists. This chapter studies the way that members of parliament in the Swedish Riksdag use social media as a tool for intra-party competition. The analysed data consist of interviews with 37 parliamentaria

Limitations and possibilities for microbial degradation of organic contaminants in aquifers

Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning: Miljögift är mat för bakterier i grundvatten Jag har undersökt bakteriers nedbrytning av organiska miljögifter i grundvatten och intresserat mig för hur den påverkas av gifternas vidhäftning till sand och bakteriernas aktivitet och mångfald. Sådan kunskap kan bidra till att förhindra gifters spridning till t.ex. drickvatten. Many factors can influence the rate of microbial degradation of organic contaminants in aquifers. Some of these factors, e.g. sorption, the presence of dissolved organic matter (DOM), biomass, redox conditions, cometabolism, microbial community composition, and activity of degrading microorganisms, are addressed in the thesis, with the ambition to gain insights for bioremediation in aquifers, and

Väckarklockor

VÄCKARKLOCKOR är en helt omarbetad och utökad upplaga av boken Väckarklockor för människor i livets väntrum. Innehållet i denna bok har vuxit fram i nära samarbete med människor som lever med långvarig smärta och olika utbränningsdiagnoser. Väckarklockorna har använts som utgångspunkt för existentiella livsnära samtal i Värkstaden, där man arbetar med ett pedagogiskt koncept för rehabilitering av
